Imagine wanting to be with someone of the same sex and then seeing news reports about a similar person being beaten to death for that reason. Imagine being immersed daily in negative language regarding homosexual relationships ("fag", "queer", "dyke", "fairy", "disgusting", "sin", "evil", "pedophile", etc.)--relationships you know you need, and which are put on a level with murder and pedophilia regularly.
The study may be flawed, and that itself might be noteworthy. If it's not, that, too is.
Actually, I read an article and it doesn't looks odd to me anymore. At first glance, it looked as too focused on someone's sexual orientation while totally ignoring personal traits of people. Now it's obvious that it's just a stats report. My bad.
